IMPORTANT NOTICE NOTES: 1) Accutemp griddle mounting; This version of the Installation Manual for the Market Forge oven model MSA-SB- 2600 includes the (4) parts (listed below) that were modified in order to accept the Accutemp Griddle being mounted on top. All ovens shipped from the Market Forge factory with a Serial Number less than #226167 will require a back fit kit, Market Forge part number 98-4162, in order to mount the Accutemp griddle. The back fit kit includes the updated version of the (4) parts listed below and installation instructions. A simple replacement of these (4) parts with the back fit kit parts will allow the griddle to be mounted on top. The tools required to perform the replacement are a slotted screwdriver and a 7/16 socket wrench. List of (4) parts that were modified to accept the Accutemp Griddle; Part Number Description 98-3571 RIGHT SIDE CHANNEL 98-3572 LEFT SIDE CHANNEL 98-3586 FRONT TOP PANEL 98-3587 REAR TOP PANEL 2) Replacement Reed Switch; This version of the Installation Manual for the Market Forge oven model MSA-SB- 2600 includes a new part number for the Reed Switch (sometimes referred to as a Proximity Switch). Due to alignment issues with the original Reed Switch a new, more forgiving Reed Switch is now being used. The new Reed Switch part number 08-6615 should be used as a direct replacement for part number 08-6308 in older model MSA-SB-2600 ovens. All ovens shipped from the Market Forge factory with a Serial Number less than #225207 will have the original Reed Switch 08-6308. These can be directly replaced with the new Reed Switch 08-6615. i

Cleaning/Preventive Maintenance... Trouble-Shooting Guide... Illustrated Parts List... Assembly Instructions... Appendix... i ii ii 1 1 2 2-3 4-6 7-19 20-23 YOUR ENERGY EFFICIENT CONVECTION OVEN MSA-SB-2600 convection ovens are electrically powered, high capacity ovens featuring high energy efficiency. These ovens are designed to radically cut power consumption, delivering the cooking power of a 16 KW oven from only 11 KW s of energy input. Improvement of energy use is made possible by a carefully designed insulating system which keeps heat inside the oven longer. A convector fan distributes heat uniformly throughout the oven interior, for fast even roasting and baking. Like all Market Forge products, MSA-SB-2600 ovens are built to the highest standards of workmanship, employing only the finest materials and components. Of course, Power Saver II ovens are fully approved by UL, and other official testing authorities. HOW THE OVEN OPERATES MSA-SB-2600 ovens operate by use of two simple controls, a power switch for turning on the fan motor and control circuit, and a thermostat for setting the oven temperature. The oven is otherwise automatic. A thermostat maintains oven temperature by cycling heating elements on and off, with temperature fluctuating no more than 20 F from the setting. Uniform distribution of heat within the oven is assured by continuous operation of a convector fan. A 60-minute and Constant Heat timer serves as an aid in using the oven, when the timer expires the heating elements shut off. To prevent unnecessary loss of heat when the doors are opened, an interlock switch stops fan operation whenever the rightside door is opened. Should the operator wish to cool the oven, opening just the left- side door will quickly ventilate the oven interior. ii

OPERATING CONTROLS & INDICATORS The controls required to operate the oven are listed in the following table together with a short functional description of each. The physical location of each control is shown in FIG.1. ITEM DESCRIPTION FUCTION 1 Thermostat Control Regulates oven temperature. Controls heating element operation. 2 Thermostat Light Indicates when the thermostat is calling for heat and the elements are ON. 3 Timer/Constant Heat Electrical timer to aid in time cooking cycles. Controls oven and constant heat mode. 4 Power Light Indicates power is ON. 5 Power/Fan Switch Three position fan switch. Controls fan speed either HIGH/ LOW or in the middle position the oven is OFF. FIG. 1 Operating Controls & Indicators 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. Check that power is available to the oven Arrange shelf positions according to the item to be cooked. Close doors. Move fan switch to HIGH or LOW. Fan should come on. Set thermostat dial to desired cooking temperature. Element indicator light should come on Allow oven to preheat for about 5-10 minutes. Preheating is complete when indicator light goes out and the buzzer sounds. Do not waste energy by turning the oven on too early. Load oven. The load should be adjacent to the oven, so the doors will be open as short a time as possible. Close doors. Set timer for desired cooking time. Buzzer will sound at end of preset interval. Oven is ready to unload. If oven temperature is to be lowered, set the thermostat to the desired temperature to cool interior. Fan will continue to run with left door open and right door closed. Where indicator light comes on, oven is at lower temperature. Close left door. When light goes off, oven is ready for use. For daily shutdown, place oven thermostat and power switch in OFF position. For extended shut- down, leave doors ajar as well. 1

CLEANING/PREVENTIVE MAINTENANCE A good preventive maintenance program in the form of daily cleaning procedures is outlined in the following steps: 1. Remove oven shelves and wash in mild detergent and water. Rinse and dry. 2. Remove left and right hand shelf supports by lifting up and out toward center of oven. Wash, rinse and dry. 3. Remove fan baffle by lifting up and out. Wash, 4. 5. 6. rinse and dry. Wash interior sides, bottom, and top with mild detergent and water. A stainless steel cleaner (not polish) should be used for the interior. Rinse and dry. Replace fan baffle, shelf supports and shelves. Wash both sides of doors, top & bottom trim using a stainless steel cleaner. Rinse and dry. TROUBLE-SHOOTING GUIDE PROBLEM Probable Cause CONVECTOR FAN FAILS TO OPERATE. REMEDY a. Power to oven is off. Locate external circuit breaker for power and place in ON position. b. Power switch off. Place in ON position. c. Right oven door open. Close Door. d. Control circuit breaker off. Place in ON position. e. Faulty circuit breaker, door interlock switch, fan motor, or wiring. Refer to wiring diagram or obtain outside service. INDICATOR LIGHT FAILS TO LIGHT WITH FAN OPERATING, THERMOSTAT SET. a. Indicator light burned out. Replace light. See service and parts manual for procedure. b. Electrical failure. Refer to wiring diagram or obtain outside service. FAN OPERATION - NO HEAT. a. Thermostat not set. Set thermostat. b. Faulty contactor, wiring, electrical failure. Refer to wiring diagram or obtain outside service. 2
